HIV in Canada: A primer for service providers

 

Youth

Key Points

  • Youth (aged 15–29 years) accounted for 23% of new HIV diagnoses in 2017.
  • Youth (aged 15–29 years) accounted for 26% of all Canadians diagnosed with HIV up to 2017.
  • Street-involved youth, youth who inject drugs, and young men who have sex with men are at higher risk for HIV.

Youth (aged 15 to 29 years) accounted for 23% of all new HIV diagnoses (545 reported cases) in 2017. Individuals between the ages of 15 and 29 years accounted for 26% (21,719 reported cases) of all diagnosed HIV infections up to 2017. However, it should be noted that symptoms for HIV may take many years to develop, sometimes as many as 10 years or more, so many people infected when they are youth will probably not be diagnosed until they are adults, once symptoms appear. For this reason, many people infected as youth may not be captured within these statistics.

In 2017, among youth with a reported/identified risk factor, 61% of new HIV diagnoses were attributed to gbMSM, 3% to gbMSM who also inject drugs, 14% to people who inject drugs and 19% to heterosexuals.

HIV is prevalent among certain populations of youth. According to national HIV estimates, the HIV prevalence rate in Canada is 0.2%. According to various national surveillance systems, the prevalence rate among street youth, youth who inject drugs, and young men who have sex with men is much higher. According to a national surveillance system of street youth (aged 15 to 24) in Canada conducted between 2009 and 2012 (E-SYS), the HIV prevalence rate among street-involved youth was 1%. According to a national surveillance system of people who inject drugs in Canada conducted between 2010 and 2012 (I-Track), the HIV prevalence rate among youth (aged 15 to 24) who use injection drugs was 3%. According to a national surveillance system of men who have sex with men in Canada conducted between 2005 and 2007 (M-Track), the HIV prevalence rate among young men who have sex with men (aged 29 or less) was 4%.
